DISH-WASHING MACHINE.

To all whom it may concern:

Be it known that 1, WILLIAM MATLo'oK CAMPBELL, a citizen of the United States, residing at Honolulu, Territory of Hawaii, have invented new and useful Improvements in Dish-VVashing Machines, of which the fol- 'machine complete,

' chines.

lowing is a specification.

My invention relates to dish-washing ma- Its ob'ect is to provide a machine which will wash, rinse, and dry dishes and discharge thesame from the machine in one operation and without the intervention of manual means further than that required to insert the dishes into the machine.

In my apparatus plates and like dishes are stood on edge and made to revolve through a succession of washing and rinsing baths and through a drier. In order to make the rovision is made" for washing all sorts of ishes other than plates, as well as knives, forks, spoons, &c.

The invention consists of the parts and the construction and the combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings -in which 7 Figure 1 is 'a plan'view of my improved dish-washing machine. Fig. 2 is'aside elevation, partially in section, of the same. Fig. 3 is a plan view of the spiral runway. Fig. 4 is a diagrammatic view of the runway in rectilinear projection. Fig. 5 is an underneath sectional view of the tray-feed.

A represents a table or stand of any suitable size 'nd-description, and 2 is a drum disposed eneath the table and suitably mounted to revolve on a vertical axis and operated by any suitable means from. any

suitable source of power, as the motor 3.

This drum is provided with a spiral runway4, intowhich the dishes are inserted throughan opening 5 in the top of the table. The plates are made to traverse the runway by revolving the drum and supporting the edge of the plate in opposition to the drum, as by means of the roller 6,Which is suitablymounted on a stationary part of the apparatus.

The runway 4 is provided with an undulating bottom, the upraised portions 7 8 of which divide the runway into a plurality of successively-arranged compartments a b 0, adapted for washing, rinsing, and drying purposes. The plate is first .mserted through the opening-5 into that portion a of the runway nearest the center of the compartirient.

to support the a revolution 0 the rum and the suitable supporting of the top edge-of the plate, as by the roller 6, the plate is made to revolve on side of the drum and finally discharged through an opening 9 in the bottom of the runway and into a suitable rece tacle 10. The bottom of therunway is pre'erably V- shaped and may be lined with rubber or other suitable soft resilient material 4 to protect the plate against injury and'to ofler sufficient friction to cause the plate to rotate.

The receptacle or box 10 is mounted on rollers or otherwise adapted'to slide on suitable guides 11. It is provided with a number of partitions and is given a 'step-by-step movement corresponding with the revolution of the drum, so that the space between the several artitions will be brought successively into ine with the slot 9 to receive the plate as it is delivered from the drum. Any appropriate means -may be employed to effect this coordinate movement of the receptacle and drum. As here shown, one edge of.

the drum has an eccentric cam 13, which engages the teeth of the rack 12 successively to advance the receptacle one plate-space at each revolution of the drum. There ma be a plurality of these rece tacles provide so that asone is filled anot er may be slid into lace to receive'each plate as" it is'delivered om the machine. f

In order to allow for the roper entry of plates into the machine and their delivery therefrom, it is preferred to give the drum an l intermittent movement permitting it to stop each time the discharge-opening 9} comes I have shown by way of illustration a mutilated gear connection 14 between the motor 2 and the drum toeifect the desired'res'ul't.

The walls of the runway in the various compartments a, b, and c are provided with suitable rubbers corresponding to the p'articticompartment a the walls a're'lined with soft rubbing-surfaces 1 5, made of sponge, felt, soft cloth, or other suitable material, bolted or otherwise secured in position and operating on the soiledsurfaces of the late to remove every vestige of dirt. The rin'sin compartment may or may not be provide with rubplate u right on; its edge. By

hers. The drying-compartment c is lined with suitable soft absorbent material 15, and this lining is so arranged on the walls that each plate will be thoroughly dried during its passage from the rinsing-compartment b to the discharge-slot 9 in the drum.

In operationa plate to be washed is inserted into the machine through opening 5 in the top of the table at the proper moment, which according to the present description is during the period of rest of the drum. Preferably the plate is inserted with its concavity toward the center of the machine, so that the cleansing-surfaces 15 on the adjacent wall of the runway will enga e the concavity of the plate tangentially, and as the plate and drum" revolve simultaneously every portion of the plate to be cleaned will be acted upon by the brushes. Passing throu h the Washing-bath the plate rises on the un ulation 7 and drops into the rinsing-water contained in compartment b, throu h which the plate is passed prior to being ried. It then rises on the undulation 8 and enters the drying-chamber c, whence it is finally discharged into the receptacle 10. The inside of the drum within the space inclose'd bythe inner walls of the run way forms a chamber 17, having a conical bottom and a central discharge 18. This chamber contains a screen or equivalent dishsupport 19, on which cups, saucers, and like dishes which need only to be rinsed maybe placed,inverted above arotary sprinkling dev vice 20, connected withany suitable source of hotwater supply. The top of the table A is provided with a hinged cover 21, which may be lifted to give access to the chamber 17. 1 This cover is closed to keep in the splash 'duringfthe operation of the sprinkler. A strip 22, carried by the drum, may underlie the crack around the cover to deflect water from the sprinklerand prevent leak around The shaft of the drum is shown as hollow and is ste ped ina bearing which has a discharge-out et registering with the previously-mentioned passage-way 18. By turnin off the water to pipe 20, by which the sprink er is run, the dishes will quickly dryby their own heat-and the contained heat of the chamber. The water from the washing and rinsin compartments a b of the runway 4 may be ischarged into the chamber 17 and through suitable valved connections 23. Water-for the compartments a b may be delivered through the valved inlet-pipe 24.

In orderflto make the machine complete and adapted for washing dishes and. pots of various descriptions, I provide a sink por tion 25, in which I arrange a suitably-mounted rotary brush 26, which is disposed radially to and. driven from the drum 2, the rotation of the brush 26 being effected by the interengagement of the gear 27 with the annular rack 28 on the upper edge of the drum. The brush 26 is of special use in cleaning dee dishes-such as pitchers, pots, kettles, an the likeand brushes of various descriptions may be employed .on the same means of the intermeshing gears 30.

It is possible that various modifications in my invention may be made without departing from the principle thereof, and I do not wish to be understood as limiting myself to my specific construction beyond what is required by a reasonable interpretation of my claims. v
